2026-06-16 Processed data and scripts for DEM analysis of thermal ratcheting and wall-load transfer in Li2TiO3 breeder pebble beds doi:10.57760/sciencedb.40197 en This dataset contains processed source data, representative LIGGGHTS-INL input files, post-processing scripts and manuscript figures supporting a discrete-element-method study of thermal ratcheting and wall-load transfer in Li2TiO3 breeder pebble beds. The data support analyses of free-surface settlement, porosity evolution, contact-network memory, wall-load histories, structural boundary protocols, regime mapping, route sensitivity, Voronoi/free-volume statistics, direct contact-force distributions, stiffness robustness, overlap audits and kinetic-energy diagnostics. The dataset is intended to reproduce the manuscript-level figures and quantitative statements. Large raw LIGGGHTS particle dump/restart files are not included in this processed-data package because of file size, but can be provided by the corresponding author upon reasonable request or deposited separately if required.
